Other moms have already mentioned the reward system... that didn't work as much with us. My DD did so well with #1, but only transitioned to #2 in the potty WHEN SHE WAS READY. It took awhile, and may require a bit of patience to wait for it to happen. Keep reinforcing it and it will happen... you're probably not too far away. My daughter started being consistent around age 3.
